PPO English name: Polyphenylene Oxide, Chinese name: polyphenylene ether. PPO PPO board stick is one of the five generic engineering plastics in the world. It has the rigidity, heat resistance, flame retardant, high strength excellent electrical properties and so on. In addition, the polyphenylene ether also has a wear, non-toxic, resistant to pollution. PPO dielectric constant and dielectric loss in the engineering plastics is one of the smallest species, almost independent of temperature, humidity, can be used for low, medium and high-frequency electric fields. PPO load deformation temperature up to above 190 ℃, brittle transition temperature is -170 ℃. PPO plastic material is used as one of the world's top five general-purpose, non-toxic, relatively low density, (PPO / PA similar products is only 1.10-1.13g / cm3), is a five-five general-purpose engineering plastics in the least dense, with good mechanical strength, creep resistance, stress relaxation, fatigue strength. PPO PPO plate rod characteristics: 1, good overall performance, can be used in 120-degree steam, electrical insulation, water is small, but there is a tendency to stress cracking. Noryl eliminate stress cracking. 2, there are outstanding electrical insulation and water resistance, good dimensional stability. The dielectric properties of plastics in the first place. 3, MPPO modified materials for PPO and HIPS blends prepared, currently on the market are such materials. 4, a higher heat resistance, glass transition temperature of 211 degrees, melting point of 268 degrees, heated to 330 degrees a tendency to break, the higher the content of PPO better heat resistance, heat distortion temperature up to 190 degrees. 5, the flame of good, self-interest, and HIPS mixed with moderate flammability. Lightweight, non-toxic and can be used in the food and drug industries. Poor resistance to rotation, for a long time in the sun will change. 6, can be blended with the modification ABS, HDPE, PPS, PA, HIPS, glass fibers and the like. Applications PPO board PPO stick: 1, suitable for production of heat-resistant parts, insulating parts, less wear resistant parts, transmission parts, medical and electronic components. 2, can be used for high temperature use of gears, blades, valves and other parts can be instead of stainless steel. 3, can be made screws, fasteners and connectors. 4, the motor, the rotor, the housing, the transformer electrical components. Polyphenylene oxide (PPO / PPE) is a high temperature heat-resistant plastic, PPO board (polyphenylene ether stick). Abbreviation PPO. Structure for the glass transition temperature of about 210 ℃, PPO rod melting temperature of 257 ℃, PPO rod density of 0.96 to 1.06 g / cm 3. Practical molecular weight polyphenylene ether from 2 to 50 000, PPO stick crystallinity of about 50%. The most prominent advantage is the height of water and steam resistance. Treatment in the high pressure steam 132 ℃ 200 times, tensile and impact strength did not change significantly, in addition it also has good dimensional stability, high insulation characteristics, PPO stick long-term use temperature of -127 ~ 120 ℃, No work load interruption up to 200 ℃, PPO stick with the general level quite thermosets. PPO stick with high impact toughness, low water absorption, high dimensional stability and less prone to creep. Frequency of its electrical properties largely unaffected loaded, it can be widely used in the electrical field. PPO bar Specifications: Sheet: 5 ~ 100mmx500 / 600mmx1000mm / 1200mm bar: 4 ~ 200x1000mm PPO stick Origin: United States GE, Germany PPO stick Color: Black
